How to load processes from Guvnor Repository?

[markboletti]

Hi all !

I'm looking for a way to load my process from the Guvnor Repository. The process has been created in the defaultPackage and according to the Web designer it's valid.

Here's how I am trying to load it:

private static KnowledgeBase readKnowledgeBase() throws Exception {

  KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

  kbuilder.add(ResourceFactory.newClassPathResource("sample.bpmn"), ResourceType.BPMN2);

  return kbuilder.newKnowledgeBase();

  }

  public void startProcess() throws Exception {

  KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();

         KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("admin", aconf);  

         String fileName = "http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST/ChangeSet.xml";

         kagent.applyChangeSet(ResourceFactory.newFileResource(fileName));

         KnowledgeBase kbase2 = kagent.getKnowledgeBase();

         StatefulKnowledgeSession ksession2 = kbase2.newStatefulKnowledgeSession();

         ProcessInstance process = ksession2.startProcess("defaultPackage.StartWKFlow");

         System.out.println("process "+process.getProcessId()+" " +process.getProcessName());

  // start a new process instance

  ksession.startProcess("com.sample.bpmn.hello",parameters);

  }

Unfortunately I'm unable to retrieve the ProcessInstance as an error "Invaild Process ID" is raised.

Has anybody knowledge how to solve this problem ?

thanks

Mark
